UNITED STATES- PATENT `JIIARLES F; EDMINSTER, OF TISKILVA, ILLINOIS.

TAN K-HEATER.

SPECIFICATION forming part of Letters Patent No. 414,800, dated November12, 1889. Application filed May 24, 1888. Serial No. 274,934. (Nomodel.)

To all whom, it may concern,.-

Be it known that I, CHARLES F. EnIvIINs'rER,

a citizen of the United States, residing at Tiskilwa, in the county ofBureau, State of Illinois, have invented certain new and usefulImprovements in Tank-Heaters, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention has relation to cattle-tank heaters employed forpreventing water from freezing during cold weather.

The objects and advantages of the invention will hereinafter appear, andthe novel i 5 features be particularly pointed out in the claim.

Referring to the drawings, Figure l is a central longitudinal sectionol' a feed-water tank and heater constructed in accordance with my 2oinvention. Fig. 2 is a similar view of amodiication of the heater. Fig.3 is a front elevation of the heater shown in lfig. l, and lfig. 4 is amodiiicat-ion in vertical section.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 represents an ordinary feed-water tank. At one side, and partly buriedinthe ground, is a heating-chamber 2, vthe upper halt` of which ishinged to the lower halt' by hinges 3o \Vithin the chamber 2 is mountelan oilreservoir 4, provided with a .burner 5 and suitable regulatingdevice (i. As shown in Fig. l, the heating device may be of the lormdescribed, or, as shown in Fig. 2, the reservoir may be located at thetop ot the chamber 2 and the burner 5 connected to the reservoir by afeed-pipe 7, and thus vapor or oil be fed to the burner. Mounted abovethe burner 5, in this instand p3? legs 5, is a 4o heat-concentratingdrum or dome 9, and surrounding the same is a water jacket or space 10,which communicates with the reservoir 1 through apipe 1l. A smaller pipe12 passes from the drum 9 through the pipe ll and into the reservoir land up above the water-level in the same. This pipe 12 may be arrangedas shown in Fig. 1, 0r it may be arranged in a tortuous manner, as shownby dotted lines in said figure.

Water iiows from the reservoirinto the Water-jacket l0, and is heatedand produces a circulation through the jacket and tank or reservoir. Theheat generated in the dome or drum 9 passes through the smaller pipelQand out at the top, thus serving to prevent the Water from freezing overand preventing the cattle from drinking. A suitable supply of oxygen isfed to the burner 5 through the medium of a pipe 13, which communicateswith the atmosphere outside of the box or chamber 2 and leads downcontiguous to said burner. A

The chamber 2 may be constructed of sheet met-al or other suitablematerial, but in this inst-ance is built ot' wood. To guard against thedanger of fire and consequent destruction of the device, I provide avalve la, which is seated in an opening or seat 15,I`o1-incdntliewater-jacket 10. This valve is held to its seat by a string or cord 17,so that should an explosion occur the cord is immediately bu rned awayand the pressure of wat-er in the jacket forces the valve from its seatand permits the Water therefrom to flow into thc chamber '2, wherebysaid chamber is Aflooded and the fire extinguished.

Having described my invention and its operation, what I claim is Afeed-water tank and attached heatingchaniber, said tank and chambercommunicating by an opening, in combination with a heating-drum providedwith an outer jacket. a portion of which projects into said opening, apipe communicating with the interior ol? said drum and extending throughsaid opening into said tank, and a lamp beneath said drum, substantiallyas described.

In testimony whereof I atti X In y si gnat u re in presence ot twowitnesses.
